His name is Draco Malfoy, at least it is now. He started out as a soul before the System he possessed rebooted, apparently after suffering a critical error. Apparently, features he had from the system were incompatible with where he was to be reincarnated, but our MC couldn't remember why. After receiving a mysterious message through his system from a god or something, someone calling him Sun Wukong, the Monkey King, the soul who would become Draco Malfoy, was left to experiment with his Mysterious System. Fortunately, his Newbie Pack gave him all seven Harry Potter books to help him prepare to enter his new world, and with that he was able to begin preparing for the eventual conflicts to come. While his memories of his previous life, or perhaps lives, appear to be missing, he sometimes finds himself just understanding things mysteriously, and he's uncertain why. He decides that after seeing all the Karma he had previously accumulated, that he must have been a good guy in his previous life or lives, so he decides to live his new life his own way and to hell with the script/story he read. He'll rise to the top of the world, exploit every advantage his system gives him, and surpass both Moldybutt and Dumbledore!
